the best way using notificationlistenerservice. introduced in android 4.3 , considerably improved lots of new features in android 4.4. should use it.

how use

step 1

you first need extend notificationlistenerservice class , implement methods.

public class simplekitkatnotificationlistener extends notificationlistenerservice {          @override         public void onnotificationposted(statusbarnotification sbn) {               //..............         }          @override         public void onnotificationremoved(statusbarnotification sbn) {               //..............          } } 

step 2

then must declare service in manifest file bind_notification_listener_service permission , include intent filter service_interface action.

<service       android:name="it.gmariotti.android.examples.             notificationlistener.simplekitkatnotificationlistener"       android:label="@string/service_name"       android:debuggable="true"       android:permission="android.permission.bind_notification_listener_service" >       <intent-filter>            <action android:name="android.service.                  notification.notificationlistenerservice" ></action>       </intent-filter>   </service> 

step 3

you must authorize user. can find in settings -> security -> notification access

intent intent = new intent("android.settings.action_notification_listener_settings");     startactivity(intent); 

step 4

use extras field information want to,

notification mnotification=sbn.getnotification();    bundle extras = mnotification.extras; 

you can lot of info class,

/**      * {@link #extras} key: title of notification,      * supplied {@link builder#setcontenttitle(charsequence)}.      */     public static final string extra_title = "android.title";      /**      * {@link #extras} key: main text payload, supplied      * {@link builder#setcontenttext(charsequence)}.      */     public static final string extra_text = "android.text";      /**      * {@link #extras} key: third line of text, supplied      * {@link builder#setsubtext(charsequence)}.      */     public static final string extra_sub_text = "android.subtext";      /**      * {@link #extras} key: bitmap used instead of small icon when showing      * notification payload,      * supplied {@link builder#setlargeicon(android.graphics.bitmap)}.      */     public static final string extra_large_icon = "android.largeicon"; 

step 5

you can data this,

string notificationtitle = extras.getstring(notification.extra_title);      int notificationicon = extras.getint(notification.extra_small_icon);      bitmap notificationlargeicon =                    ((bitmap) extras.getparcelable(notification.extra_large_icon));      charsequence notificationtext = extras.getcharsequence(notification.extra_text);      charsequence notificationsubtext = extras.getcharsequence(notification.extra_sub_text);
